OIL-CAN.

QPEOIFICATION formingpart of Letters Patent No. 670,509, dated March 26,1901. Application filed January 26, 1901. Serial No. 44,849. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. H. ERWIN, acitizen of the United Statesof America, and a resident of York, county of York, State ofPennsylvania, have invented certain new and useful Improvements inOil-Cans, of which the following is a full, clear, and exactdescription, in which- Figure l is a vertical section of the cancomplete; and Fig. 2, a detailed section enlarged, showing'theactuating-spring and adjustable stop.

The object of this invention is to provide simple devices forcontrolling the flow of oil from the can, so that it may be accuratelyfed in copious or limited amounts, as occasion may require, whereby allwastage of oil is prevented, as more fully hereinafter set forth.

Referring to the drawings, a designates a valve-rod extending up throughthe spout and provided with a conical valve 1) onits upper extremity,which normally seats in the conical end of the spout, and therebynormally shuts off the flow of oil at the extreme end of the spout. Theother end of rod (1 is bent laterally at c and straight upward at d,this upward extension passing up through an opening in the removablescreW-plugc of the can. The upper end of rod dprojects above plug a andis threaded for the reception of a sleeve f, which is in turn externallythreaded for the reception of a threaded stop-nut g. The lower end ofsleevefworksin an opening in plug 6, and between a loose follower h,abutting against the lower extremity of said sleeve, and aninward-turned flange t', formed on the lower end of a tube j, is anactuatingspring 7a, which surrounds rod 61 and is inclosed in said tubej. The tube j depends from plug 0, and its lower open end is practicallyclosed by rod at, so but little oil can enter said tube when the can isinverted. As will be observed, the spring normally keeps the valveclosed by pressure upward upon the lower end of sleeve f through themedium of the follower, and the tension of the spring may be increasedor decreased by screwing the sleeve downward or upward on rod d, as

the exigencies may require.

To prevent the valve being forced against its seat at the end of thespout so hard as to controlled. To vary the amount of oil fed,

the stopgis adjusted upon sleeve f, the higher it is adjusted the morecopious being the feed. In this manner the feed may be regulatedpositively and will not depend upon the varying pressure of theoperators finger upon the sleeve f, thereby enabling the feed to bepositively regulated to a nicety to suit the work and to avoid wastageand scattering of the oil.

It will be observed that the device is so ex-' tremely simple inconstruction as to permit it to be applied to the ordinary hand-oilersnow in use without adding materially to the cost of their manufacture.

It will be observed that the valve-rod a is thinned between the valve band bend a, so as to render it flexible. The object of this is to enablethe rod to conform to the curvature of a curved spout Where such form ofspout is employed.

It will be further observed that a feature of importance lies in thefact that the tube j extends into the can and not only affords a itingthe movement of the valve-rod. A further featurethat contributesmaterially to the utility is that the regulating-stop is accessible fromthe exterior of the can.

Having thus fully described my invention, what I claim is- 1. In ahand-oiler, a can provided with a spout, a valve-rod extending up intothe spout from the interior of the can, a rod connected to saidvalve-rod inside of the can and extending to the exterior of the can, atube inclosing said rod and extending into the can, a spring inclosed"in said tube, a sleeve casing for the spring, but also a stopforlimthreaded on said rod exteriorly of the can i 2. In a hand-oiler, acan provided with a removable cap or plug carrying a spout, a valve-rodextending up into the spout and connected to an upward-extending rodextending to the exterior of the can, an externally-threaded sleevethreaded on the upper end of said extension, an actuating-spring, and anadjustable stop-nut screwed on said sleeve, for the purpose set forth.

3. In a llaud-oiler, the combination of aean provided With a spout, avalve-rod extending up into the spent, a tube extending into the can andcoinciding with anopeuing therein,a vertically-W0rkiug rod extendingthrough
